I don't know if those are available - but looking through the coursework, if you have time, it has a few projects that you could build yourself and have a in house demonstration. I purchased a Circuit Playground from Adafruit and it came pretty quickly and I ran through a few of the lessons just to see. Additionally, if you have advanced students, this could be a side project for them to "pilot" and "help figure out what might trip up other students". Hopefully once more classes have done the curriculum, there will be some videos available.
For videos outside of Code.org, a couple people have made things and shared on Youtube as possibilities, which might not be the exact projects - but show the possibilities!
